Abstract
A method and apparatus for estimating a state of a battery. The method includes obtaining a measured voltage of a battery from a sensor connected to the battery, obtaining an estimated voltage of the battery from an electrochemical model stored in a memory, estimating an aging variation of the battery based on the measured voltage and the estimated voltage, and updating an aging parameter of the electrochemical model using the aging variation.
